甲烷无氧直接制备烯烃/芳烃研究进展(II)

Research progress in the direct, nonoxidative conversion of methane to olefins/aromatics (II)

  • 摘要: 在“碳达峰、碳中和”的背景下,甲烷无氧直接制备烯烃/芳烃具有零二氧化碳排放、100%碳原子利用和富产氢等优势,是碳一化学和催化领域中一个热点研究课题。本综述基于作者在甲烷无氧直接制备烯烃/芳烃反应的研究工作,结合2018−2021年的相关文献,对目前甲烷无氧芳构化反应和甲烷无氧直接制备烯烃、芳烃和氢气反应的世界各国研究现状进行综合评述。重点讨论活性位确认、反应中间体、反应机理、催化剂性能及提升等工作。最后对甲烷无氧直接制备烯烃/芳烃的研究前景进行了展望。

     

    Abstract: Direct, nonoxidative conversion of methane towards olefins/aromatics is a hot topic in the background of “carbon peak, carbon neutrality”, owing to zero CO2 emissions, high carbon atom utilization efficiency and hydrogen production. In the present paper, the advances of methane dehydroaromatization (MDA) and direct nonoxidative conversion of methane to olefins, aromatics, and hydrogen (MTOAH) are reviewed, based on our research works and the publications from 2018 to 2021. The determination of active sites, reaction intermediates, reaction mechanism, catalyst modification and improvement were considered. Finally, the future prospect was given for the direct nonoxidative conversion of methane to olefins/aromatics.
